Abstract

The invention discloses a precise nitrogen pressure gauge, which comprises a pressure gauge body. A connection sleeve is communicated with the bottom of the pressure gauge body, a threaded pipe is communicated with the bottom of the connection sleeve, and an inner cavity of the pressure gauge body is provided with an information processing unit. The pressure gauge body, the connection sleeve, the threaded pipe, the information processing unit, a power supply module, an acquisition unit, an information feedback unit, a data storage module, a prompt unit, a cell phone APP, a pressure sensor, a temperature sensor, a humidity sensor, an airflow sensor, a signal transmitting module, a buzzer, a red alarm flashing lamp, a green warning lamp, a fixed baffle and a gasket cooperate to solve the problem that the existing precise nitrogen pressure gauge does not have an overpressure alarm function. The precise nitrogen pressure gauge has the advantages of an overpressure alarm function, enhances the safety of the precise nitrogen pressure gauge, and enhances the practicality of the precise nitrogen pressure gauge.

Description

technical field [0001] The invention relates to the technical field of pressure gauges, in particular to a precision nitrogen pressure gauge. Background technique [0002] Pressure gauge (English name: pressuregauge) refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used. It is used in almost all industrial processes and scientific research fields. Water and gas supply systems, vehicle repair and maintenance factories and other fields can be seen everywhere, especially in the process of industrial process control and technical measurement, because the elastic sensitive components of mechanical pressure gauges have high mechanical strength and easy production, making mechanical pressure gauges Pressure gauges are used more and more widely. [0003] Precision nitrogen pressure gauge is a kind of pressure gauge, which is widely used in nitrogen processing equipment and nitrogen st...
